GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 286,170, dated October9, 1883. Application filed March 29, 1883. (No model.)

To all whom it may concern:

Be it known that I, Josnrn G. Beams, a citizen of the United States,residing at Leechburg, in the county of Armstrong and State ofPennsylvania, have invented a new and use ful Improvement in the Methodand Machinery for Burning Gas; and I do hereby declare the following tobe a full, clear, and exact description thereof, reference being had tothe accompanying drawings, forming a part thereof.

This invention consists in an improved apparatus by means of which gasesmay be ad mixed with an equivalent amount of air previous to thecombustion of the Figure 1. in drawings is a sectional. view of my airand gas mixing apparatus with airvalve. Fig. 2 is a side view of same.Fig. 3 is a detail. view, showing the manner of attaching the valve B tothe stem of valve E.

In the drawings, A is the gas-supply pipe. B is the valve for regulatingthe flow of (l is air-mixing apparatus. 1) is the dischargepipe. E is aconical valve for regulating the proper proportion of airintothcmixing-chamber. F is the miXing-chamber. gg are open ings for thepassage of air into the mixingchamber F. H is a sleeve placed on thehollow stem of the conical valve E, so to hold the valve down againstthe bottom of the mixingchamber F.

In the construction of this apparatus, the mixing apparatus 0 and theconical val ve may be cast of brass or of other metal. The base of themixing-chamber is bored out and the valve E turned up to fit it. Thesleeve 7 H is then put on, and the gas-valve Bis screwed on suflicientlyloose, so as to allow the mixingehamber to move around the valve 10. Theholes 9 r g are then bored through the mixing-chamber and the conicalvalve. hen this is done,'the apparatus is ready for use.

In the practice of this method and apparatus for burning natural gas,the mixing apparatus having been connected to the supplypipe, and nearto the furnace, fire-place, or burner, and the discharge-pipecommunicating with the furnace, fire-place, or burner, the valve B isopened so as to allow the desired amount of gas to pass into themixing-chamber F. The conical Valve E is then adjusted so as to allow afull and free passage of air through g g g The pressure of the gaspassing into the mixing chamber will cause a suction of the air through9 g g g, and the air and gas thus intimately admixed will be forcedforward through the discharge-pipe I), and from thence into thecombustiouchamber. \Vhen the air and gas appears at the point designedfor combustion, it is ignited. The conical valve is then turned aroundso as to nearly close the air-inlets g g g 9, when a smokeflame willappear. The valve should then be gradually opened until the'smokedisappears entirely, and a white flame is caused at the point ofcombustion. he volume of the flame and quantity of heat evolved may beregulated by the amount of gas let through valve P.

The natural gas is composed of a number of hydrocarbon compounds with anaver age composition of eighty-seven per cent. of carbon and thirteenper cent. of hydrogen, which will require two hundred and thirtytwopounds of oxygen to convert the eightyseven pounds of carbon to carbonicacid, and one hundred and four pounds of oxygen to convert the thirteenpounds of hydrogen to steam, E10,) and to get this three hundred andthirty six. pounds of oxygen will require thirteen hundred andforty-four pounds of air to consume one hundred pounds of such gas. Itwill. thus be seen that nearly thirteen and a halfpounds of air isrequired to produce a perfect coumbustion of one pound of natural gas,and where the gas is used in large volumes it is impossible tothoroughly admix sufficient air at the point of combustion to secure aperfeet combustion; but by my method of admixing the air and gasthoroughlyprevious to its exit at the point of combusti 011 aninstantaneous and thorough combustion ensues. The gas and air may alsobe admixed by means of a siphon or injector or other apparatus; but inpracticeI find most excellent results by the use of apparatus shown inthe drawings. a My invention may be applied to burning natural gas,gasoline, or made from coal for light to very great advantage, as by theprevious admixture of an equivalent of air with the gas, the gas and airis thoroughly commingled, and when they emerge from the burn or aperfect combustiontakes place and smoke is absolutely prevented. Forthis purpose I ber, such as shown in Figs. 1 and 2.

This invention is intended to be applied more particularly to naturalgas, which ordinarily escapes at a pressure of from ten to two hundredpounds per square inch. Such g'as, when burned in the ordinary manner,rushes forth with such force as to escape ma'ny feet from the mouth ofthe burner before any combustion can takeplace; but by means of mydevice a sufficient quantity of air may be admixed with said gas torender combustion independent of the air about the end of the burner.Furthermore, when gas under great pressure is burned in the ordinarymanner immense volumes of smoke are produced, showing that the gas isonly partially consumed, whereas with my apparatus a clear, steady, hotflame may be produced.

I am aware that an apparatus for commingling air and gas previous to thecombustion of the latter is not broadly new. I am furthermore aware thatin such apparatus it is not new to combine with the shell of a mixm-chamber rovided with orifices a sleeve having similar orifices adaptedto register therewith, and thus form'a valve for the admission of air.Such construction I do not therefore claim; but

WVhat I do claim is I11 an apparatus for mixing air and gas previous tocombustion, the combination, with the induction-pipe A and eduction-pipeD, of the mixing-chamber shell 0, having conical end provided withorifices, the conical valve E, having a hollow st'em screw-threaded atits outer end, and provided with orifices registering with those inshell 0, the sleeve H, and the valve 13, screwed to the outer end of thevalve stem, all arranged and operated in the man- 0 ner and for thepurposes described.
